A Support contact for an identity provider or service provider is the primary contact for handling user problems. The name and email address of each Support contact is published in the federation metadata and should not be regarded as private.
A Support contact may be an individual, or it may be a generic email address (such as a mailing list) with a generic title (such as 'Help desk'). It may be the same contact as the Technical contact or Administrative contact. Note that a Support contact email address is intended to be used by people inside or outside your organization, so please do not limit the email domains that it will accept emails from.
A Support contact may be appointed or replaced by an Administrative contact, a Management Contact or a Signatory Contact.
